Featuring a 2.50-inch inlet and a 2.50-inch outlet, this muffler is designed to create adequate healthy backpressure, contributing to optimal engine performance. It promises to deliver a superior and aggressive sound that is sure to turn heads. Installation is straightforward, described as a simple clamp-on process that involves cutting the existing muffler. With the right tools, installation is estimated to take approximately 1-2 hours and requires light to moderate mechanical skill. This muffler offers universal fitment, meaning it can be adapted to a wide range of vehicles. However, it is important to note that some adaptation may be required during installation to ensure a proper fit.
